Here is a start.  "t" is the parser, "tt" tests how it works.  Depending on
exactly what you are doing, you may have to play with the quotes, or it may
be impossible to handle quotes correctly in the shell alone.

/c> cat t
#!/bin/sh
for Arg in "$@"
do
        if test -f "${Arg}" -o -d "${Arg}"
        then
                NewArgs="${NewArgs} '$(cygpath -w "${Arg}")'"
        else
                NewArgs="${NewArgs} '${Arg}'"
        fi
done
echo NewArgs="${NewArgs}"
echo no eval, no quote
tt ${NewArgs}
echo no eval, quote
tt "${NewArgs}"
echo eval, no quote
eval tt ${NewArgs}
echo eval, quote
eval tt "${NewArgs}"
/c> cat tt
#!/bin/sh
for A in "$@"
do
        echo "$A"
done | cat -n
/c> t 123 /c/cygwin/bin/ls.exe '45 67' /c/Program\
Files/Mozilla/Firefox/firefox.exe /c/Program\ Files
NewArgs= '123' 'c:\cygwin\bin\ls.exe' '45 67' 'c:\Program
Files\Mozilla\Firefox\firefox.exe' 'c:\Program Files'
no eval, no quote

Subject: Strategy to process all tokens on a line through "cygpath -w",
ignoring non-path tokens

I have a situation where I have a command line that I need to preprocess
with "cygpath -w", changing all tokens which represent paths to convert
them to their windows equivalent.  All other tokens should pass through
unchanged.  Is there already a canned solution for this?  What would be
a reasonable strategy to get this done?
